Proviron (DHT, Masterlone, Masterolone, Mesterolone)

Proviron (Masterolone) è una forma orale di 1-metilato DHT (methyl-diidrotestosterone). This is very strong androgen which is 3-4 times more effective than “normal” testosterone, it possesses no anabolic characteristics and no capabilities of converting to estrogen. One would imagine then that mesterolone would be a perfect drug to enhance strength and achieve some progress. Unfortunately, there is a control mechanism for DHT in the body. When levels get too high it is being converted to an inactive compound. This inactive compound can equally be transformed in the opposite direction to dihydrotestosterone by the same enzyme when low levels of DHT are detected. But this means that very large amounts of this substance are useless to achieve muscle hypertrophy. Very common usage is fighting estrogen just like with Tamoxifen Citrate or Clomiphen. Provironhas four distinct applications in bodybuilding.First of all, proviron serves as anti-estrogen, it prevents  aromatization of other steroids as a process and also partially blocks estrogen receptors. In this instance its action differs from tamoxifen, which only blocks  estrogen receptors. Thus side effects such as gynecomastia and increased water retention are successfully eliminated. Proviron hits the root of the problem, while Tamoxifen fights only symptoms and should be used for longer period until all excessive estrogens are washed out of the body.
The second application is based on expanding the capacity of testosterone. 97-98% of testosterone in the body of a healthy person is inactive and bound to certain proteins. Proviron in this case replaces testosterone, thus more of latter is being released into the blood and helps to build muscle mass.

Thirdly, mesterolone is added in pre-competition cycles to increase the rigidity and quality muscle volume. It also decreases water retention in the body, giving the user a visual effect of a dry, high-quality, lean muscles. Proviron is often used not only among bodybuilders, but even the actors and models, who use it to acquire the necessary sportive form  before the shooting. Just like the another methylated DHT structure called drostanolone, mesterolone is particularly strong in achieving this effect.Finally, Proviron is used for recovery of sexual activity during the cycles of steroids such as trenbolone and nandrolone, which decrease libido. Proviron is also commonly prescribed by doctors for people with low levels of testosterone, or patients with chronic impotence.Mesterolone is preferred by many athletes because it has virtually no side effects on men. In large doses it can cause some virilization symptoms in women. Doses of 25 and 250 mg per day shall be applied without adverse effects. 50 mg per day is usually sufficient to reach goals for any of four applications that we mentioned above. Thus, there is no need to increase the dose.

Gli atleti maschi dovrebbero preferire Proviron a Nolvadex. Con Proviron l'atleta ottiene una migliore durezza muscolare, poiché il livello di androgeni aumenta e la concentrazione di estrogeni rimane bassa. Ciò è particolarmente evidente quando ci si prepara per una competizione insieme alla dieta.

Tuttavia, si dovrebbe essere consapevoli che la perdita di forza causata dalla diminuzione della produzione naturale di testosterone dopo il ciclo non è curata. L'atleta dovrebbe usare altri farmaci come HCG e clomifene per questo.

Dosaggio e utilizzo

Proviron è un composto molto efficace, il dosaggio giornaliero di 50 mg è sufficiente sebbene alcuni uomini ne assumano 100 e persino 250 mg / giorno. L'atleta normalmente prende una compressa da 25 mg al mattino e l'altra alla sera. In alcuni casi è sufficiente anche una compressa da 25 mg. La combinazione di 50 mg di Proviron al giorno e 20 mg di Nolvadex al giorno si traduce in una soppressione quasi completa degli estrogeni. Tuttavia, tieni presente che gli estrogeni non sono un male assoluto, ma svolgono anche un ruolo importante nella costruzione muscolare. La soppressione completa degli estrogeni significa guadagni inferiori, quindi si dovrebbe mantenere un equilibrio e diminuire il livello di estrogeni solo fino al punto in cui non produce effetti collaterali ma produce comunque quelli positivi.

In the past athletes used it throughout the whole season to make dry and fit outlook all the time, however, we don’t advice such practices nowadays. Clenbuterol / albuterol (ventolin) can do the same but with less side effects.

Impilabile

Proviron is an oral 1-alpha-alkylated substance mostly used as  an anti-estrogen drug. Mesterolone may actually contribute to gains.  It is taken daily in 50-100 mg doses.

The best stack is certainly with testosterone. This results in qualitive, lean gains as free testosterone levels are increased and less converted to estrogen.

Naturalmente, il proviron viene utilizzato anche in molti altri stack, ad esempio con dianabol (methandrostenolone), boldenone undecanoate e nandrolone per ridurre le attività legate agli estrogeni e aumentare la durezza muscolare.

Combo of proviron with boldenone makes dead lock for a cutting stack. Sometimes it’s even become possible to add deca into that cutting stack, preferably along with winstrol. It’s good idea to use proviron with nandrolone, because nandrolone temporarily decreases libido.

Effetti collaterali con proviron

When athlete do it for more than 10-12 weeks it may slightly increase liver values although in general proviron is well tolerated by it. Side effects of Proviron for men with a dose of 2 – 3 tablets are very small, so that Proviron, in combination with a steroid cycle can be relatively safe to be taken over several weeks.

DHT can increase blood pressure. High dosages may lead to premature baldness and sexual overstimulation, which leads to prolonged erection. Since this state is painful and can cause penis damage, it makes sense to reduce the dose or discontinue its use altogether.

Only 34% of recipients observe minor decrease in endocrine glands function. Proviron did not stop work of HPTA (glands) for noone who took the drug for a year at a dose of 150 mg / day. In general it’s pretty safe and has little impact on the work of HPTA.

Non vi è alcun effetto sulla velocità di LH (ormone luteinizzante) e FSH (ormone stimolante) alla dose di 100-150 mg / giorno.

Proviron non sostituisce Clomid come terapia ormonale, ma non causa anche problemi.

L'impatto del mesterolone non produce alcun cambiamento nei livelli di steroidi, ormoni tiroidei, gonadotropine e prolattina.

Uso femminile

Le atlete dovrebbero essere caute durante l'utilizzo di Proviron, poiché non esclude tutti i possibili effetti collaterali androgeni. Si consiglia alle donne di non assumere più di una compressa da 25 mg al giorno. Dosi più elevate e un uso prolungato per più di 4 settimane aumentano i rischi di virilizzazione. Le atlete che non hanno problemi con Proviron, ottengono buoni risultati assumendo 25 mg di Proviron al giorno e 20 mg di Nolvadex al giorno. Dicono che in combinazione con una dieta accelera la combustione dei grassi e il rapido indurimento dei muscoli.

Female athletes who naturally have higher estrogen levels,  often add Proviron to steroid cycle, which results in increasing of muscle density. In the past female athletes did proviron whole year in order to look lean, especially before contests and starring. Nowadays, clenbuterol / albuterol do the same work, because they do not cause virilization effects.
